DRIVING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 656,985, dated August 28, 1900.

Application filed October 24, 1899. Serial No. 734,666. (No model.)

To all whom it may concern.-

Be it known that I, WALTER JOHN LE BAR- RON, of South Barre, in the county of Washington and State of Vermont, have invented a new and Improved Driving Apparatus, of which the following is a full,"clear, and exact description.

This invention relates to an apparatus for transmitting power to various driving devices. I have shown it as applied to marine propulsion, to which use I consider it best adapted.

This specification is the disclosure of one form of my invention, while the claims define the actual scope thereof.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional elevation of a vessel equipped with my improvements, showing a windmill for furnishing power. Fig. 2 is a plan view of the shifting friction-pulley. Fig. 3 is a elevation of the controlling-gear. Fig. is a sectional detail of the friction-pulley, and Fig. 5 is an end elevation of the pulley and of the carriage on which the same is mounted.

A windmill-tower 6 is lnounted on the deck 7 of a vessel and carries a wind-wheel 8 and its appurtenances, by which a shaft 9, mounted vertically in the tower, is driven. This shaft extends down to the foot of the tower and carries a large friction-wheel 10, formed with a cavity 11 in its center. A propellershaft 12 is mounted longitudinally in the vessel and carries at its front end a balance- Wheel 14, its rearend being projected through the stern-post of the vessel to carry a propeller 15 in the usual manner.

Mounted below the shaft 12 and frictionwheel 10 are two rails 16, on which is arranged to move a carriage 17, the rails 1G being disposed fore and aft, so that the carriage 17 may be adjusted beneath the wheel 1l. This carriage 17 carries revolubly the hollow journals 18 of a frictionwheel 19, which wheel is splined on the propeller-shaft 12 and arranged to engage with the under face of the friction-wheel 10. Now it is clear that by adjusting the carriage 17 the speed at which the friction-wheel 19 is driven from the wheel 10 may be regulated and also the direc tion of revolution may be reversed. It will further be seen that the friction-wheel19 may be moved to lie in the cavity 11 in the wheel 10, in which position there will be no transmission of motion between' the two wheels and the shaft 12 will be at rest.

For adjusting the carriage 17 I provide a rod 20, mounted in suitable guides 2l and formed at its r'ear portion with rack-teeth 22, which mesh with a pinion 23, carried on a shaft 24, mounted ina suitable framing 25. A perpendicular shaft 26 is juxtaposed to the shaft 24 and connected therewith by miter-gears 27, and this shaft 26 is connected with a third shaft 28 at the top of the gear 25 by means of ruiter-gears 29. The shaft 2S carries a handwheel 30, facilitating the manual revolution of the shaft 28, and consequently the shafts 26 and 24, thus moving the rod 2O backward and forward and adjusting the carriage 17 with its wheel 19. j

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a driven shaft, a friction-wheel splined on the said shaft, a carriage having connection with the frictiomwheel, to move the same longitudinally of the shaft, a track on which the carriage runs, means for transmitting movement to the carriage, a frictional driving-wheel engaged by the firstnamed friction-wheel, the first-named friction-wheel being movable along the face of the drivingwheel, to regulate the movement imparted to the driven shaft, and means connected with the driving-wheel, to propel the same.

2. In a driving apparatus, the combination of rails, a ca rriage mounted to slide thereon, a friction-wheel having a hollow axle, the ends of which are mounted to turn in the carriage, and a frictional driving-Wheel engaged with the first-named friction-wheel, such firstnamed friction-wheel being movable with the carriage along the face of the drivingwheel, for the purpose described.
